Abstract

Durability of concrete is possibly related to externally-induced chemical attacks in addition to internally-induced deterioration. Externally-induced chemical attacks can be derived from various sources according to environmental conditions under which concrete structures are existing. The present study investigates the characteristic concrete deterioration and formation of secondary minerals by external chemical attacks under certain environmental condition. Petrographic microscope, SEM, EDAX, XRD analyses were conducted to identify secondary mineral formation and micro-structural analyses.
